Benchmark description

SPEC CPU2006* is a benchmark to measure system efficiency during integer and floating point operations. It consists of an integer test suite containing 12 applications and a floating point test suite containing 17 applications, which are extremely computing-intensive and concentrate on the CPU and memory. Other components, such as disk I/O and network, are not measured by this benchmark. SPEC CPU2006* contains two different methods of performance measurement: The first method, "speed", determines the time required to complete a single task. The second method, "rate", determines the throughput, i.e. how many tasks can be completed in parallel. Both methods are additionally subdivided into two measuring runs, "base" and "peak", which differ in the way the compiler optimization is used. The "base" values are always used when results are published; the "peak" values are optional. The chart above shows base integer rate throughput performance as measured by SPECint*_rate_base2006.

Product and Performance Information

1. Software and workloads used in performance tests may have been optimized for performance only on Intel® microprocessors. Performance tests, such as SYSmark* and MobileMark*, are measured using specific computer systems, components, software, operations, and functions. Any change to any of those factors may cause the results to vary. You should consult other information and performance tests to assist you in fully evaluating your contemplated purchases, including the performance of that product when combined with other products. Source: Published and Intel internal data as of February 14, 2011. Please see configuration details links above for system configuration details. For more information go to www.intel.com/performance.

2. Relative performance for each benchmark is calculated by taking the actual benchmark result for the first platform tested and assigning it a value of 1.0 as a baseline. Relative performance for the remaining platforms tested was calculated by dividing the actual benchmark result for the baseline platform into each of the specific benchmark results of each of the other platforms and assigning them a relative performance number that correlates with the performance improvements reported.

4. Intel® Hyper-Threading Technology (Intel® HT Technology) requires a computer system with a processor supporting Intel® HT Technology and an Intel® HT Technology-enabled chipset, BIOS, and operating system. Performance will vary depending on the specific hardware and software you use. For more information including details on which processors support Intel® HT Technology, see www.intel.com/products/ht/hyperthreading_more.htm.

6. Intel® processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. See www.intel.com/content/www/uk/en/processors/processor-numbers.html for details.
